This September 1995 photo shows a Surtseyan plume at Ruapehu during the eruption through Te Wai ā-Moe (Crater Lake), forming the dark cock’s-tail plume above the vent and a gas-and-steam plume to the left from the lake water. Two lahar paths descend the Whakapapa ski field on the northern flank in the foreground. A third lahar traveled down the eastern flank Whangaehu Valley.
A gas-and-steam plume rises above the Ruapehu Te Wai ā-Moe (Crater Lake) during Surtseyan activity in September 1995 with two lahar deposits down the Whakapapa ski field on the northern flank. By early October almost all of the crater lake water had been removed.
